That one you showed last is definitely a Bafang clone and orbitally geared Daniel. There are a couple of these alternative product manufacturers (blatant copiers), it seems part of Chinese culture that they see nothing wrong in this.

Your first link shows a switching photo in which the motors are different in the two shots. The first with the black sidewalls looks like one another member said is internally geared but very weak. The second silver wall type looks like a direct drive, but it's not possible to be certain.

Very happy. I am running cheap SLA's at the mo, so very heavy, but covering hilly 16 miles in around 45 minutes, traffic dependant - I have the 1000W, not the 500.

The supplied battery connector melted immediately and I have replaced a throttle that began to malfunction, but both of those problems have been reported on here. I am not consciously using it in the wet, but have been caught out more than once and everything still works.

My view is that I'm doing this experimentally on the cheap. The conversion kit cost just over £200 delivered, so I am prepared to buy another for spares if something breaks.

As I remarked before, if direct drive those narrow and small diameter motors are unlikely to have much torque and
power. They'd be completely outclassed by the Tongxin roller drive and Bafang geared motors. Some buyers have
been disappointed with the poor performance of even the larger diameter direct drives that appear in these cheap
kits. Basically D.D. motors do need a reasonable diameter and a high enough supply voltage to have a acceptable
performance that compares with the popular geared hubs like the Bafang type.

You only have to look at what e-bike manufacturers fit to see the position. They avoid the cheap direct drive
types and almost universally use the more expensive internally geared hub motors. Direct drive motors can be ok,
the BionX being a reasonable size one that is used by the odd manufacturer, but it's a very expensive and
sophisticated setup.

Well, there are rumours on Endless Sphere and the Golden Motor's own forums that they are outsourcing the manufacturing of internal elliptical geared units (probably old stock from Suzhou Bafang, actually), but some official representative has been denying this...

Anyway, GM seem to have problems with their controllers, they are now trying to push sales of their new "Magic Pie" controller, which is quite exiting technically but equally flawed...apparently.
